I finally decided to root my phone last night. I installed Sapphire 0.8.4 and although my battery life seems to be significantly worse. Is this normal when installing a new ROM? I'm going to install SetCPU tonight when I get home from work and try to set up some profiles. Should that improve battery life? When I was running stock 2.1, my Battery Left widget always said i got about 15 hours full battery life. I haven't had a chance to calibrate it with the new ROM but it's saying my full battery life is less than 7 hours. Besides SetCPU, is there anything I can do to improve battery life? Thanks.
